HOWTO make Gecko-based browsers usable

Gecko is a rendering engine used by a whole range of browsers, including Galeon, Seamonkey and Firefox. Many of the extentions made for Gecko-based browsers work in all of them, but some of the plugins only work in one particular browser.

These are extentions you much likely want if you are using a Gecko-based browser:

Webservers deliver more than just the web page asked for when a web browser (or other application) delivers a web-page. Live http headers is a great plug-in which makes the headers visible in Firefox in a variety of ways. This is specially handy if you are setting up a hidden Tor service and want to know just how much information the web-server actually gives a visitor about it's configuration (and other bits of information you may want to hide if the goal of running a hidden service is to keep the services location hidden)
